Update the "Refund" section in Swipe Games Public Integration Adapter API page. The documentation clarify that when sending a 200 OK response to a /refund request, this should always have a valid body.
Add documentation about 30-day limit for finite free rounds campaigns. Free rounds with a validUntil date must not exceed 30 days. Infinite free rounds (no validUntil) are still supported.
Made returnUrl parameter optional in /create-new-game. The field is only used when games are launched via redirect (no iframe), so it should not always be required.
